PROBLEM TO BE SOLVED: To obtain the signal light which has high visibility and no indistinguishment and perplexes neither a partially colorblind person nor a colorblind person by using one signal light and constituting the signal light so that it turn blue, yellow, and red, shows an arrow, and blinks by itself automatically. SOLUTION: The signal light A uses at both sides by one lamp, a lens diameter is 330 mm, and a cathode-ray tube of television is used as a light source to emit blue, yellow, and red lights under electric control. Data are so inputted that even the arrow, etc., can be shown at the same time in addition to the colors. For a partially colorblind person, a round mark in blue, a triangle mark in yellow, and a cross mark in red are added, thereby recognizing them at first sight. Further, the human-figure mark is not used for a sidewalk light and the same marks with the round mark in blue, the triangle mark in yellow, and the cross mark in red are used. Instead of a conventional support rod at the upper part, a light collection plate 4 for light power generation is fitted. This serve as the support rod. |
